[Coco] C VS Basic Coco

[Bill Pierce]

I did a lot of "attempts" to convert DECB code into Basic09 back in the 80s/90s and I found there is a LOT of syntax changes that have to be made, especially when it comes to graphics as Basic09 graphics require calling an external subroutine where DECB graphics are built in commands.
That being said, yes, DECB could be converted to Basic09 with the proper syntax conversion. Just be prepared for a lot of work.

Yes you can write any program in a text editor and as long as the syntax iscorrect it will load and run in Basic09. Even a DECB program will runprovided the syntax has been modified to be accurate for Basic09. There arenot many differences so syntax Corrections should be few. You would have toadd the appropriate Dimension statements in order to ensure that yourvariables are of the type necessary. Without Dimension statements allvariables default too real type and string. Strings are only defined by usewith a dollar sign character as the last character of the variable name.All other variables without Dimension statements default to real type.Also, each program is called a procedure and Basic09, and is required tobegin with the procedure statement:PROCEDURE myprogramnameWayneOn Feb 15, 2018 5:19 AM, "Francis Swygert" <farna at att.net> wrote:> Date: Wed, 14 Feb 2018 08:28:00 -0800> From: Wayne Campbell <asa.rand at gmail.com>>> Basic09 brings a lot to the table.
